Domoticz

You could do this via Domoticz.. but strongly advise not to go that way...
Opentherm thermostats are not that expensive... why would you you use your "current" on/off thermostat ?

A long time ago Newwolf suggested this code.

I also had problems with my domoticz and otgw, but this was a SD-card problem.
At the moment it is working flowless in my setup.

Maybe you can/want to test it without domoticz as client, but run it from command line.

Code:

### Download OTGW
mkdir /home/pi/otgw/
wget -N http://otgw.tclcode.com/download/otmonitor-ahf -P /home/pi/otgw/
chmod +x /home/pi/otgw/otmonitor-ahf

### Make config file

nano /home/pi/otgw/otmonitor.conf

web {
enable true
port 8081
nopass true
}
connection {
device /dev/ttyUSB0
type serial
enable true
}
server {
enable true
port 7686
relay true
}

### Run it
/home/pi/otgw/otmonitor-ahf --daemon -f "/home/pi/otgw/otmonitor.conf" &

### Kill it (if needed)
killall -9 otmonitor-ahf

Connect Domoticz or OTGW-monitor to it's IP-address and port 7686

If you want it to run on reboot follow the next steps:

### Edit
sudo nano /etc/rc.local

### Add
printf "Starting OTGW"
(sleep 20;sudo /home/pi/otgw/otmonitor-ahf --daemon -f "/home/pi/otgw/otmonitor.conf)&

Hoping you can solve your problem with this.

I have OTGW from Nodo-shop running with a wifi module NodeMCU and see the all the devices in Domoticz. However I'd like to use otmonitor as well. If I use the setup above the script looks for the USB connection. Can anyone help me please to edit?

Code: Select all

connection {
device /dev/ttyUSB0
type serial
enable true
}

Code: Select all

connection {
device 192.168.0.125
type serial
enable true
}

Doesn't work...

It is just the one or the other.

Running OTGW in combination with a Remeha Calenta + iSence thermostat. All went smooth for a couple of days, but I noticed a few days ago that when the boiler is not heating I still get a lot of switching on Flame_on and CH_Active channel. Is anyone familiar with this issue? My iSence doesn't show a start of the boiler.

Could this be your hot-water boiler maybe?

No, doesn't look so. It also has a 5 minute delay between switching, more or less. I'll try to reboot my OTGW later this day, maybe that solves this issue.

Powerup the otgw and esp, wait about 2 minutes to be sure everything booted. Then use the reset button on the otgw, wait, and after that the esp is getting good data.

Sorry for reacting on an old post, but I recently ran into this same issue when I upgraded my OTGW with and ESP8266 (D1 mini) a couple of days ago. DaWauZ's tip solved my problem, without the reset I only see cryptical OTGW codes in the log, not real device updates. Apparently the OTGW is in the wrong "operation mode" when it does this, at least I read this somewhere. But why is this incorrect mode corrected with a reset, and not by powering it up from off state? Is there another way to restore normal operation when the power has been unplugged for a while? I tried sending PS=1 yesterday, but this didn't seem to help.

Yes, that topicwww%2Edomoticz%2Ecom%2Fforum%2Fviewtopi ... are_type=t is useful but my difficulty here is they use a lan connection and i have wifi connection via NodeMCU.
I think it has to do with that specific passage

Code: Select all

connection { device /dev/ttyUSB0 type serial enable true }

. What language is it written in? Maybe that helps me searching in the right direction.

Dear people
I need some assist
I have bought the otgw from
Nodo-shop.nl
And its working perfectly till now.
After addind the ch_pressure i starting to get trouble.
My otgw is reporting some weird characters so i would reflash the otgw.
Using otgw and windows 10 laptop (uses before for flassing so drivers etc are fine)
Now the otmonitor is reporting that the flashing is failing and i have to manually reset the opentherm gateway.
If anyone of you know how to reset this please let me know!

Posted: **Thursday 04 April 2019 19:07**

I don't know for sure what is meant, but there is a possibility to reset the OTGW by temporarily shorting two specific terminals, see picture (terminals are marked with "RST"). I soldered a button on them, sometimes my OTGW (with ESP8266) is reporting weird codes in Domoticz and a reset always solves this.

Posted: **Thursday 04 April 2019 19:28**

How long did you bridged them?
30 seconds or just a small push for a sec?
Did you shutdown the otgw before bridging those 2 or in runningstate?

Sorry for my screwed english im a dutch man haha

Posted: **Thursday 04 April 2019 19:31**

Just short them for a second or so in on state
(Gewoon een seconde of zo kortsluiten terwijl hij aan staat

)

Posted: **Thursday 04 April 2019 20:22**

Did you connect it to the laptop before resetting or just only on psu?

Cuz when i short then all lights are flashing and i stop shorting them but seems like he wont reset at all.
I have connected it to the otmonitor and powersupply but doesn’t seems to do the trick
see attachments for the problem i have

Hi all,

Since yesterday I have an OTGW connected trough LAN. Connecting it to Domoticz was easy and I'm receiving data from the Remeha. So far so good.
A lot of devices are created, including the setpoint. Now here's the thing, if I change the setpoint nothing happens!
Could it be that TOON is the problem?

My setup:
Remeha Avanta - OTGW (nodo-shop)-TOON_powersup. - TOON.
Domoticz: Stable
OTGW: 4.2.5

I don't think it's a Domoticz issue, if I use the Opentherm Monitor program I can't do it either.
All help is welcome!

Hi, in which mode is your otgw running ?
Monitor or gateway??
You can find this info when you connect otmonitor to the otgw and press f7 in otmonitor.exe

It's running in Gateway-mode.

Posted: **Thursday 18 April 2019 10:53**

Try switching between gatewAy and monitor mode. So setup the otgw to run as monitor cose application resort otgw and then put it back to gateway mode.
Also make sure that your domoticz has a connection with the toon to change te values in the toon
You should be able to find some information across the internet
Also i could assist you by setting up these connections if youre in the netherlands

I tried, but nothing works. Still receiving a lot of data, but it looks like I can't overrule the thermostat.

Is the device toon configured in domoticz,
For some devices you need to create an api connection to modify/overrule these settings.

If you want you could sent me an pm so i could assait you, i guess youre in the netherlands and could speak dutch. So it will be easier to contact directly so i could assist you by configuring the api controlled connection to overrule the toon
